This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.
When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:
q1_td=terrorist_data%>%group_by(iyear)%>%summarise(No_of_Terrorist_attacks=n())
q1_ggplot=ggplot(q1_td,aes(x=iyear,y=No_of_Terrorist_attacks))+
geom_area(fill="light blue")+
geom_point(col="black",size=0.9)
ggplotly(q1_ggplot)
You can also embed plots, for example:
Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
